Toolbar - tool tips

The following code
BOOL CMainFrame::OnToolTipNotify( UINT id, NMHDR * pNMHDR, LRESULT * pResult )
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
UINT nID = pNMHDR->idFrom;
if (pTTT->uFlags & TTF_IDISHWND)
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);
if(nID)
{
// pTTT->lpszText = MAKEINTRESOURCE(nID);
// pTTT->hinst = AfxGetResourceHandle();
// return(TRUE);
}
}
else
{
strcpy(pTTT->szText,"Ruby Red GSC-XXX\nRuby Red");
pTTT->lpszText = NULL;
pTTT->hinst = NULL;
return TRUE;
}
return(FALSE);
}

Gets executed when I have my cursor over one of my items in the toolbar but the tooltip does not get displayed at the toolbar button or on the status bar of the app. Why ?

I figured it out, I needed to add:

pTTT->lpszText = pTTT->szText;

then the tip displayed by the button but not the status bar of the app.

In your CMainFrame class there is a variable as

CStatusBar m_wndStatusBar;

Now to set the text on your status bar use

m_wndStatusBar.GetStatusBarCtrl().SetText("Your Text",0,0);

A simple client to server

What i want to be able to do is send text from one client to its server. I need a client which is done by tcp. I've seen some of the chat rooms programs but as I'm all new to this its too over my head. I need a simple program. Please help us out Confused | :confused:

Try to read some MSDN documents about Windows Sockets API or MFC class CSocket or CAsyncSocket. You should understand the the mechanism of TCP first. If you wanna use a simple way to realize your program, use MFC CSocket would be your choice. But Windows Sockets API would be better for developer. Good luck.

Is VC++ 5.0 code compatable with WinXP?

9-Jan-05 8:28

I am wondering if the MFC code generated by VC++ 5.0 will run correctly, for the most part, on WinXP.

How about serial port usage in XP. Are there any issues there?

Thanks
John

Yep, no reason why not, if it's a correctly written program.

No, unless the user running the program doesn't have sufficient privileges to open the serial port.

Hi feroz20!

There are surely other and perhaps better ways to do it but you can try the following:

At first get the CWnd* from every control using GetDlgItem(int nID). With these pointers you can call SetWindowText(LPCTSTR lpszString) to change the control's text.

For example:

GetDlgItem(IDC_BTN_MYBUTTON)->SetWindowText(_T("New button text"));

My language files are plain text files (.txt) so everybody can modify them easily, even without an IDE. At program startup I load the appropriate language file an set the caption of every window control. Same thing when the user changes the language - I just load the other language file and reset the window controls.

Works perfect for me... Wink | ;)

the best to do it, is to use multiple resource files, one for each language use.

each resource will be in a DLL and will be loaded when the application starts (, or after a user select a menu item )

have a look at :

Drag&Drop problem: ListCtrl inside a Group Box

sps-itsec469-Jan-05 6:23

9-Jan-05 6:23

Implementing Drag&Drop from the explorer to a CListCtrl isn't very difficult. But I have a big problem with those da*n group boxes:

If my ListCtrl is surrounded by a group box the ListCtrl acts not as a drop target. The group box that has not the WS_EX_ACCEPTFILES flag seems to swallow the message. I can remember something about a flag for the group box to let all window messages through but right now I cannot find anything on the net.

Thanks a lot for your help!

Change the z-order of the controls so that the listctrl is above the group box.

Try using:

#define _WIN32_WINNT 0x0400
#include <windows.h>

at the top of your program. This should include the declaration for IsDebuggerPresent(), along with the other debugger functions.

Try starting here[^]. That's a list of debugging functions.

Example:

if (::IsDebuggerPresent()) {
    ::OutputDebugString("Execution reached debug point 1.");
}

Admittedly, this is a trivial example. One nice thing about using the debugger functions is that you can use them even when you run code compiled for release under the debugger.
